59 = j + 29
59-29=j+29-29
30 = j
(or you could rewrite it as j=30)
hope this helps!! :)
Just multiply the tops together and the bottoms together :)
Answer:
C. 301
Step-by-step explanation:
Since the store marked up the price by 115%. You need to first find what is 100% of 140 and then 15% of 140. 100% of 140 is obviously 140. To find 15% of 140, you take 10%, which is 14, then add half of that which is 7 to 14. 15% of 140 is 21. So you add 140 and 21; it gives you 161, which is 115% of 140. Once you add 161 to 140, it gives you a total of 301.
Answer:
Step-by-step explanation:
pool tables are rectanglar
Perimeter = 2L + 2W = 2(L+W) ---->>> Perimeter/2 = L + W =
Perimeter/2 - W = L
Area = L×W
Two equations and two unknowns and L is substituted into the area equation
---->> Area = (Perimeter/2 - W) x W
Area = (Perimeter x W)/2 - W² solve for W
Area = 36 and Perimeter = 26
36 ft² = (26)( W)/2 ft - W² ft²
36 ft² = 13W ft - W² ft²
W² - 13W + 36 = 0 quadratic equation factor solve for W
(W - 4)(W - 9) = 0
There are two roots
W - 4 = 0 and W - 9 = 0
W = 4 and 9 W = 9 it doesn't make sense needs to be < L
Perimeter/2 - W = L
L = 26/2 - W
= 13 - 4
L = 9 ft and W = 4 ft
